6.6 Checking the direction of rotation of the sewing drive

CAUTION:

Before the special sewing machine is started it is essential to check the direction of rotation of the sewing drive.

Switching it on can cause damage if the direction of rotation is incorrect.

The arrow on the belt guard indicates the correct direction of rotation.

The direction of rotation of the direct-current positioning actuator is set to run from right to left by the pre-set value of the relevant parameter in the control. Even so, the direction of rotation must be checked before the machine is started. A possible procedure is as follows:

First lock the sewing foot in the up position

(see Operating instructions, section 6.13).

DA220C control

–

The plugs of the set-point generator, motor, motor sensor and operating panel (if present) must be plugged in (see section 6.5).

–

Unplug the 37-pin plug of the upper part of the machine.

–

Turn on the main switch. The operating panel shows “Inf A5” or “A5”, which means that no valid Autoselect resistance has been detected and the maximum speed will therefore be limited.

–

Press the pedal slightly forwards; the drive turns: check the direction of rotation.

–

If the direction of rotation of the drive is incorrect, parameter 161 at “technician level” must be set to 1. See section 7.1.4.

–

Turn off the main switch.

–

Plug in the 37-pin plug of the upper part of the machine.

6.7 Checking the positioning

Needle positions are correctly set prior to delivery, but they should still be checked before starting the machine.

NB:

The sewing foot must be locked in the up position (see Operating instructions, section 6.13).

The machine must move to an intermediate halt in position 1 (needle down). See section 7.1, LED 7.

Position 1

–

Turn on the main switch.

–

Briefly push the pedal forwards and return it to its original position. The needle moves to position 1 = handwheel point “F”.

–

Check the position of the needle.

Position 2

–

Move the pedal forwards, then fully back.

–

The needle moves to position 2 = handwheel point “C”.

–

Check the position of the needle.

If either or both needle positions are incorrect, they must be corrected: see section 7.1.5 or 7.2.7.

6.8 Machine-specific parameters

6.8.1 General

The functions of the sewing-drive control are determined by the program and the parameter settings.

All parameter values for the relevant machine class and subclass are correctly set prior to delivery. This entails changing some pre-set control values (e.g. the maximum speed). If the control is replaced, the machine-specific parameters must be restored to their correct values. See section 7.1.6, 7.2.8 or 7.3.9.

6.8.2 Autoselect

The control “recognises” which machine series is connected by measuring the Autoselect resistance in the machine. Autoselect selects control functions and the pre-set parameter values.

Caution: If the control fails to recognise a valid Autoselect resistance (or any at all), the drive runs only with the so-called emergency operating functions to prevent machine damage.

6.9 Master reset

A master reset (see section 7.1.7, 7.2.9 or 7.3.10) resets all parameters to their pre-set values. After a master reset the machine-specific parameters must be restored to their correct values. See section 7.1.6, 7.2.8 or 7.3.9.

7. Operating and adjusting the DC1500/DA220C direct-current positioning actuator

Operation

The DA220C control contains all operating components necessary to switch functions and set parameters. It can be operated without an operating panel, but seam programming is not possible.

The V810 and V820 operating panels (optional equipments) can also be connected to the control. Seam programming can be carried out with the V820 operating panel.

A detailed description of the control can be found in the “EFKA DC1500/DA220C control 5300” operating instructions.

DA220C control functions

The functions of the DA220C control are determined by the program and the parameter settings. With the correct parameter settings the control is ideally matched to the class and subclass of the machine. The parameter values are pre-set in the controls. For each class and subclass some parameters must be changed from their pre-set values. All parameters are correctly set prior to delivery.

Access authorisation for command entry

To prevent the unwanted alteration of pre-set functions there are three levels of command entry.

Access:

-theoperator at “operator level” with no code

-thetechnician at “technician level” and “operator level” with a code.

-themanufacturer at “manufacturer level” and all lower levels with a code.

–

Press “E”: its associated parameter value, e.g. “002”, is displayed.

–

Press “+”: the parameter value is increased.

–

Press “-”: the parameter value is reduced.

–

Press “E”: the next parameter, “0.0.1.”, is displayed.

–

Press “E”: the value of parameter “0.0.1.”, e.g. “004”, is displayed, and so on. In this way all the operator-level parameters can be displayed and changed one after the other. After the last parameter programming at operator level terminates. You can leave programming at operator level at any time:

–

Press “P”: the same parameter, “0.0.1.”, is displayed.

–

Press “P” again to leave programming at operator level. The value for the maximum speed appears in the display, e.g. “480” for 4800 rpm.

–

On termination of programming at operator level the changed values are saved.

7.1.1.2 Calling and changing operator-level parameters directly with the

–

DA220C control

Turn on the main switch. The value for the maximum speed appears in the display, e.g. “480” for 4800 rpm. Press “P”: the first parameter, “0.0.0.”, is displayed. Press “>>”: the first figure of the parameter flashes, “0.0.0.” Press the “+”or“-” keys to change the value of the flashing figure. Press “>>”: the second figure of the parameter flashes, “0.0.0.” Press the “+”or“-” keys to change the value of the flashing figure. Press “>>“: the third figure of the parameter flashes, “0.0.0.” Press the “+”or“-” keys to change the value of the flashing figure. The required parameter is set. Press “E”: the value of the set parameter is displayed, e.g. “on”. Press “-”toswitchfrom“on”to“oFF”. Press “+”toswitchfrom“oFF”to“on”. Press “E”: the next parameter is called. Once a parameter has been set the next one can be called and changed, or

programming terminated by pressing “P”. The value for the maximum speed appears in the display, e.g. “480” for 4800 rpm.

7.1.2 Reducing the maximum speed with the DA220C control

The maximum speed can be reduced to adapt it to particular applications. During sewing, and if the machine halts, the maximum speed is shown in the display.

The three-figure value displayed must be multiplied by 10. While it is displayed the maximum speed can be changed by pressing the “+/-” keys. The adjustment range lies between the values of parameters F-111 (maximum) and F-121 (minimum). See sections 7.1.4 and 7.1.6.

NB: there are two settings for the maximum speed, the value of parameter 111 and the reduction in maximum speed with the “+/-” keys. The lower value always has priority. If the maximum speed is reduced with the “+/-” keys, an increase in the value of parameter 111 takes effect only if the reduction is cancelled during sewing by pressing the “+” key.

Caution: the maximum speed (the value of parameter 111) should not be set higher than the figure shown in the parameter sheet (in the accessory kit) for machines of the relevant class and subclass.

Setting positions 1 and 2 Prerequisite:

The reference position has been set (see section 7.1.5, “Setting the reference position”).

NB:

The position values are pre-set, so there is normally no need to set them. The pre-set values (see the parameter sheet in the accessory kit) are equivalent to the number of increments after the reference position (in the correct direction of rotation). One revolution of the motor shaft is equal to one revolution of the handwheel , equivalent to 512 increments.

The positions are: P1E = handwheel at point “F” = position 1. P2E = handwheel at point “C” = position 2. P1A = about 100 increments after P1E (important for internal control functions). P2A = about 100 increments after P2E (important for internal control functions). If the positions have to be reset, proceed as follows:

–

After entering the technician-level code (see section 7.1.4): Press the “E” key: the first technician-level parameter, 1.0.0., is displayed.

Turn the handwheel in the correct direction until “P2E” in the display changes to increments. Turn the handwheel to point “C” (position 2E).

–

Press the “E”key.“P1A” appears in the display.

–

Turn the handwheel in the correct direction until “ P1A” in the display changes to increments. Turn the handwheel about 100 increments beyond position “P1E”to position “P1A”.

–

Press the “E”key:“P2A” appears in the display.

–

Turn the handwheel in the correct direction until “ P2A” in the display changes to increments. Turn the handwheel about 100 increments beyond position “P2E”to position “P2A”.

–

Press the “P” key twice to terminate position setting and leave the programming level.

–

Check the positions: see section 6.7.

NB:

If position checking establishes that, for example, positions 1 and 2 are being “overrun” by about the same amount with respect to the setting, the reference position can be advanced by this amount.

7.1.6 Setting machine-specific parameters with the DA220C control

7.1.6.1 General

The sewing-drive control functions are determined by the program and the parameter settings.

Parameter values are pre-set by the drive manufacturer prior to delivery. For each class and subclass a number of technician-level or even manufacturer-level parameters must be changed so that the control exactly matches the machine. The relevant parameters are listed in table 7.1.6.3 and the parameter sheet (see table 7.1.6.2). The parameter sheet is in the accessory kit. All parameters are correctly set by Dürkopp Adler prior to delivery.

7.1.6.2 Autoselect

The control “recognises” which machine series is connected by measuring the Autoselect resistance in the machine. Autoselect selects control functions and the pre-set parameter values. If the control fails to recognise a valid Autoselect resistance (or any at all), the drive runs only with the so-called emergency operating functions to prevent machine damage (see “EFKA DA220C 5300” operating instructions).

Autoselect classes control parameter sheet resistance sewing drive

** A function module is a part of the control that handles one of the machine’s facilities, e.g. raising and lowering the transport roller. The control contains two function modules, A and B.

Each function module has the following hardware:

–

one output (A or B), e.g. to control a solenoid valve

–

one input ( A or B), e.g. to connect a key

–

one output for an LED (A or B), e.g. displaying a switch status.

Each function module can be assigned various functions by the software. Each function module has additional parameters, e.g. to activate counts or switch functions after the thread is cut.

CAUTION:

Great care must be taken when changing parameter values, as an incorrectly-set drive control may damage the machine.

7.1.7 Master reset with the DA220C control

Any parameters that have been changed are restored to their pre-set values by a master reset.

–

Turn off the main switch.

–

Press the “P” key, hold it down and turn on the main switch until “C.o.d.” appears.

–

Release the “P”key.

–

Enter the technician-level code. See section 7.1.4.

can be individually assigned to each seam. For a description see the “EFKA DA220C 5300” operating instructions.

8. Fullness control in classes 275-142342 and 275-742642

8.1 Checking the basic control setting

Once the machine has been set up the basic control setting

should be checked and adjusted if necessary. In order to change the basic setting the machine must switched on while pressing the “F” key.

As soon as the green LED above the “F” key lights up the key can be released: the LED flashes. On completion of the internal system check the “special functions” selection is displayed.

The various special functions are called by pressing keys 1 to 7; the green LEDs above the keys indicate the function called. The following sections describe special key functions 2, 4 and 5. The other special functions are described in the Servicing instructions. Press the “F” key to leave special functions and switch to normal operation: the LED above the key goes out.

8.1.1 Setting the LED and display brightness

After calling special functions (see section 8.1), press the key 2. All the LEDs are switched on. The brightness can be adjusted to any of 8 levels by pressing the “+/-” keys. Press the “F” key twice to save the brightness setting and switch to normal operation.

Brightness is factory-set to level “03”.

8.1.2 Moving to the reference position after each thread cut

When the machine is switched on the step motor that sets the overfeed length moves to the reference position. In order to check the position of the step motor more often, the step motor can also be moved to the reference position after each thread cut. The procedure is as follows:

–

After calling the special functions (see section 8.1) press the 4 key.

–

The function can now be switched with the +/- keys:

–

display 00 = move to the reference position only when the machine is switched on.

–

display 01 = move to the reference position after each thread cut.

–

Press the “F” key twice to save the setting and terminate the function.

The machine is factory-set to “00”.

8.1.3 Activating the next seam sequence when the thread is cut

When the program contains fullnesses the next seam sequence is normally activated by the thread cut. There are three options when the thread is cut. The procedure for selecting them is as follows:

–

After calling special functions (see section 8.1) press the 5 key.

–

The function can now be switched with the +/- keys: display 00 = the next sequence is not activated when the thread is cut.

display 01 = the next sequence is activated after each thread cut.

display 02 = as 01, but when change-of-direction is switched on the direction is changed in the first and last sequence by the first thread cut and the next sequence activated by the second thread cut.

–

Press the “F” key twice to save the setting and terminate the function.

The machine is factory-set to “02”.

8.2 Rotation in the reference position

Every time the machine is switched on the step motor that sets the overfeed length rotates to the reference position, then back to the current overfeed length. This is necessary for the display to coincide with the overfeed length.

Caution: danger of injury

When checking the reference position take care to avoid moving parts.

The procedure for checking this function is as follows:

–

swivel the machine back

–

switch it on

–

after the internal system check the step motor rotates to the reference position

–

the LED in the inductive key briefly lights up when the reference position has been reached

–

the motor then rotates to the current overfeed-length position.

9. Pneumatic connection
